“FOR THE INCREASE AND DIFFUSION 
OF KNOWLEDGE AMONG MEN" 
THE UNITED STATES INTERNATIONAL EXCHANGE SERVICE 
UNDER THE DIRECTION OF THE 
SMITHSONIAN INSTITUTION 
JN EFFECTING the world-wide distribution of its first publications, the Smithsonian 
Institution established foreign agencies by means of which it was enabled to mate¬ 
rially assist institutions and individuals of this country in the transmission of their 
publications abroad, and also foreign societies and individuals in distributing their 
publications in the United States. 
In more recent years the Smithsonian Institution has been charged with the duty 
of conducting the official Exchange Bureau of the United States Government, 
through which the publications authorized by Congress are exchanged for those of 
other governments; and by a formal treaty it acts as intermediary between the learned ( 
bodies and scientific and literary societies of this and other countries for the recep¬ 
tion and transmission of their publications. 
Attention is called to the fact that this is an international and not a domestic 
exchange service, and that it is designed to facilitate exchanges between the United 
States and other countries only. As publications from domestic sources for ad¬ 
dresses in Hawaii, the Philippine Islands, Porto Rico, and other territory subject to 
the jurisdiction of the United States do not come within the designation “interna¬ 
tional, ” they are not accepted by the Institution for transmission through the service.
